1.2 Sampling Values of Devices
The MICRO/I samples values of target devices at a regular interval or when a value of device changes.
●
Sampling Value of Devices at a Regular Interval
When sampling values of devices (D100 to D102) at a 5 minute interval (Time: 300 seconds) with the data storage
amount in the data storage area is set to 3, the MICRO/I samples Data Log data as follows.
1
5 minutes after data sampling starts, the MICRO/I stores the values for devices D100 to D102.
2
10 minutes after data sampling starts, the MICRO/I stores the values for devices D100 to D102.
3
15 minutes after data sampling starts, the MICRO/I stores the values for devices D100 to D102.
4
20 minutes after data sampling starts, the MICRO/I stores the values for devices D100 to D102.
Since the data storage amount in the data storage area is set to 3, the oldest data is deleted in order to make room
for the newest data.
